[Expression.Error] We cannot convert the value "" to type List
I cannot find out what the error means.
I am following step by step manual from the link:
https://sqldusty.com/2016/04/26/power-bi-and-the-bing-maps-api/
First I found latitude and longitude for provinces. The query worked fine.
However in the second step, when I try to add latitude and longitude to county I got the error.
Can anyone help me?

HI paweldm,
As tjd said, the error message show that it can't convert null value, perhaps you can try to replace these null value to a default value before your operation.

I believe that it's telling you that you have a null value in one of your lat/long fields and it can't convert that to a decimal number.

Hi,
I checked my pna table and there are no empty cells.
I have found however some errors in new calculated columns with location parameters.

It's not a good habit to cross post questions on another forum if the topic is still active here
At least you should mention the cross post.
